This study aims to evaluate the water balance of the crop mix of the Czech Republic and the tendencies of its development during the period 1961–2019. For calculating water deficits, methodology from ČSN 750434 (Czech technical standards) was used and on its basis, the deficits of the ten most frequently represented crops of the Czech Republic were calculated. These results were then put into the context of the development of precipitation totals and the development of average annual temperatures in the observed period. Furthermore, statistical tools were used for the identification of relationships between the observed variables and the tested hypotheses to verify the statistical significance of the observed changes. The results show that the overall irrigation deficit nearly doubled in Czech agriculture when comparing the averages for the periods 1961–1970 and 2010–2019. This change was evaluated as statistically significant. Furthermore, there were also statistically significant increases in water deficits in the cases of wheat, barley, rye, oats, legumes, and rapeseed. The sowing areas of the observed crops recorded statistically significant change in all cases. Only in the case of wheat, maize and rapeseed were there increases in sowing area, specifically 146%, 642.4%, and 1132.7%, respectively. For other crops, a decrease in sowing areas was observed. This finding points to decreasing commodity diversity in Czech agriculture, which, in combination with a high degree of intensification and selected agrotechnical practices, contributes to a lower retention capacity for the soil and landscape to retain water, which in turn influences the overall water balance of the Czech agrarian sector.

The paper deals with an agriculture production analysis of biogas plant in the Czech Republic and evaluates the effect of input-factors and their relevance. Cobb-Douglas functions for crop, livestock and total agriculture production are used. Econometric models are used for structure and magnitude determination of land and labour factors at individual farms, which lead to an increase of production defined in scenarios. Estimations are based on cross-section data. Results indicate statistical significance and the economically highest effect of land and fixed assets on the total agriculture production. The results of first period model show, that there is preferably a need for an increase of fixed assets when enlarging the livestock production. There is an increase of the importance of wages in total and livestock production in 2011 compared to 2010. The crop production is dependent on land are in the most, but the model must be rejected because of parameters intensity and economic justification. Quantification of relationships among variables can be used for planning of the whole production or its components.

The Eu

Being a member of the EU, today the Czech Republic is not entirely dependent on domestic production of food and farming commodities. Since borders inside the EU are open, particular commodities can flow without any tariff measures. But food self-sufficiency belongs to internal factors of national security and therefore it deserves sufficient attention. The aim of this article is to evaluate, based on an analysis, the self-sufficiency rate of the Czech Republic and Poland in selected commodities of crop production between marketing years 2000/2001–2009/2010, with special attention to the most important and cultivated commodities – basic cereals, oilseeds, corn and potatoes. Based on analyses of self-sufficiency rate it can be concluded, that both countries can be considered as stabilised with restpect to rate of self-sufficency of selected crops – none of the presented groups falls under 80%. For most described commodities the trend of self-sufficiency rate in the Czech Republic and Poland is stabilised or growing. Only production of potatoes is coming close to critical treshhold in CZ, therefore national strategies should be put in place to maintain the self-sufficiency rate above the critical limit. After an analysis of internation trade it can be concluded that the Czech Republic is specialised exporter of not-processed commodities but country significantly falls behind Poland in competitiveness of processing of commodities.

Food And Feed

A new food and feed self-sufficiency model for the Czech Republic (RESTEP) was applied for the evaluation of possible adverse climate impacts uniformly reducing crop production by 5, 10, 20, and 30%. The situation was simulated for the whole country and four different agriculturally important regions. Biomass production modeling confirmed that for the whole country, the food self-sufficiency is secured up to 20% of yield decline for most crops, but even 5% yield decline of silage maize would lead to its shortage in animal feeding. On the other hand, regional results vary significantly. Regions Jižní Morava and Střední Čechy shown oversupply of feedstuff allowing them to cover the demands of cattle and pigs up to 20% or 30% decline of yield, respectively. The opposite model represents the Vysočina (VY) region which is not able to cover the demands from own sources even at the baseline scenario. The acreage extension of maize is not possible due to erosion risk restrictions at 25% of arable land at VY. The possible solution consists of extension acreage of alfalfa and clover or finding other plants sufficient for feeding as well for biogas facilities in regions rich in biomass energy consumers.

The aim of the paper is to assess the situation and development of Czech agriculture by the production and economic ratios of a sample of farms. The development is evaluated using a database of farms from the Czech Republic since 2000, divided by the share of land included in the LFA. The year 2011 revealed a significant improvement in economic indicators over the previous year. A positive profit appeared in 95% of enterprises and economic results approached the results of 2007. An important trend is the reduction in the number of workers, when in 2011 the number of workers was equal to 70% to that in 2000, while labour productivity is increasing annually by an average of 7%. In the structure of production, the average farm revealed a revenue growth of crop production, the revenue from livestock production was declining, although the opposite trend appeared in mountain areas. In all categories of farms, there is a growing dependence on subsidies. Although the year 2011 was the second most productive since 2000, the profit after deducting subsidies was reached by 13% of farms only.

Gliadin Alleles

Using vertical electrophoresis, a set of 22 biotypes heterogeneous according to their gliadin alleles as well as their low-molecular-weight (LMW) and high-molecular-weight (HMW) glutenin subunits were identified in 10 winter wheat varieties registered in the Czech Republic. The effects of individual biotypes and their specific allelic compositions on 16 grain quality parameters were investigated. Inter-varietal differences in particular quality parameters (Zeleny sedimentation, farinograph water absorption, several values of the solvent retention capacity test) were significantly greater than the differences detected among biotypes of each variety. Special attention was given to the LMW glutenin subunits and gliadin alleles and to mutual interactions responsible for significant differences in the tested grain parameters. The results revealed at least one case of significant differences in grain quality parameters among biotypes of eight heterogeneous wheat varieties. This work unambiguously indicates that the high prevalence of wheat biotype(s) with significantly poorer values in some grain parameters can also decrease the expected technological quality of the original wheat variety. In particular, multi-line wheat varieties carrying alleles Glu-B1 (6+8) and Glu-B1 (7+9) or Glu-B3j and Glu-B3g can indicate the possibility of some significant changes in grain quality parameters.

The Impact

The presented article is based on research evaluating the impact of cluster organisations on the financial performance of member entities. The author’s doctoral thesis examines whether there is a difference in the financial performance of cluster organisations created through the bottom-up and the top-down approaches, under the conditions existing in the Czech Republic. Both types of clusters that meet the condition of maturity (established before or in 2012) and of a high degree of activity were selected for the research. The financial performance of member business entities was assessed using the following indicators: ROA, ROE, ROS, EVA, EVA/employee and EVA/sales. The aim of the research was to demonstrate whether public support for clusters would be reflected in member entities’ better financial performance. The final part of the paper then summarises and discusses the findings.

Level Of Significance

This paper aims to examine the similarities between innovative companies in the Engineering and the Electrotechnical industry in the Czech Republic. The main question is whether R & D spending in companies with eco-innovation leads to a rise in turnover even in a short period of time. The paper uses the Burea Van Dijk database – Amadeus as a data source. This data source includes 186 large enterprises with information on employee’s numbers, turnover, sector affiliation and R & D expenditure. A binomial test of statistical significance was used for the comparison of the two groups of companies. The authors find that approximately one-third of enterprises record revenue slump. There was no statistically significant difference at the level of significance α = 0,05 between the shares of enterprises with eco-innovations that showed a decrease in turnover.

The purpose of the pilot project Senot&iacute;n (1993&ndash;2000) was to prove the methods of revitalization of sub-mountain headwater area (0.38 km<sup>2</sup>) in the Novobystřick&aacute; Vysočina Highland (610&ndash;725 m a. s. l.) in the Czech Republic. This area was tile-drained and ploughed in 1985. Seven underground clay shields newly constructed in 1995 stopped the function of the tile drainage. Four balks prevented the surface and subsurface runoff. These adaptations improved water retention capacity of the whole catchment, which is demonstrated using an example of runoff formation in the revitalized area. A typical storm rain (total 15 mm, duration 5.6 h, max. intensity 4 mm/20 min) and the consequent runoff was analysed, including the role of the soil in the runoff retardation and water retention. The runoff started in two hours since the rain beginning. The retention reached 98% of the rain total. The runoff lasted for 85 h. The concave-upward shape of the falling hydrograph limb indicates that the maximum retention capacity of the studied catchment is high.
